ROTATING HEAT-TRANSFERRING DEVICE.

SPECIFICATION forming part of Letters Patent No. 769,557, datedSeptember 6, 1904.

Original application filed May 2'7, 1902, Serial No. 109,197. Dividedand this application filed February 7, 1903. Serial No. 142,323. (Nomodel.)

To (LZZ whom, it nuty concern:

Be it known that I, LEOPOLD VON MAY, a subject of the Emperor ofAustria-Hungary, and a resident of Ungarisch-Ostra, Mai-graviate ofMoravia, Empire of Austria-l-Iungary, have invented a new and usefulImprovement in Rotating Heat-'lransferring Devices for Cooling,Distilling, Heating, Evaporating, and Condensing Liquids and biases, ofwhich the following is a specification.

The invention relates to that class of rotating heat-transferringdevices to be used for cooling liquids or gases, for condensingexhaust-steam, or for heating or distilling liquids, which comprises agroup of pipes each connected at one end with one of two chambers and atthe other end with the other of said two chambers, which chamberscommunicate one with an inlet-pipe and the other with an outlet-pipe,the said inlet and outlet pipes being arranged in line with each otherand constituting shaft-journals, about the common axis of which thewhole structure of chambers and pipes rotates.

The improvement consists in the novel structure hereinafter describedand claimed embodying such pipes and chambers and journals, the saidimprovement having been described in my application, Serial No. 109,197,for United States Patent filed May 27, 1902, of which this applicationis a division.

Figures 1 and 2 of the drawings represent vertical sections at rightangles to each other of a rotating heat-transferring device embodying myinvention.

a designates a casing for containing liquid to be heated or cooled or aheating or cooling liquid, represented of substantially cylindricalform.

(Z and c are two short hollow shafts arranged in line with each otherand fitted to rotate in stuffing-box bearings (Z e*'in opposite sides ofthe casing a. Between these shafts (Z and c and connecting them there isa box which is divided by a longitudinal partition 7L2 into two chambersh h, situated side by side. The

With the hollow shaft 6.

the chamber 71., at the right, communicates with the hollow shaft (2,but not with the one (Z. The only communication between the two chambers[L la is through the numerous group of heating or cooling pipes m m,which have a curvature approximately concentric with the axis of thealined shafts (Z and a and which almost surround the said chambers 7t7t.

On that side of the casing (a at which the hollow shaft (Z projectsthrough the stuflingbox (Z there is provided a stationary chamber 9,with which the hollow shaft (1 communicates and to which the heating orcooling medium or the liquid to be heated or cooled or steam or vapor tobe condensed is introduced at f. The open outer end of the hollow shaft0 is connected by a stufling-box c with a stationary outl.etpipe 1-. Thesaid shaft 0 has applied to it any means for rotating it a gear p, forexample. This rotation carries with it the whole structure a (i ll, 7/ mm, of which the hollow shafts (l c constitute journals. The heating orcooling medium or the liquid to be heated or cooled or the steam orvapor to be condensed introduced through f and g enters into and passesthrough the hollow shaft or journal (Z, thence into the chamber lb,whence it circulates through the numerous heating or cooling pipes m mto the chamber it, through which it or its condensation product passesto the hollow shaft or journal 0, which forms an outlet to the pipe r.

The box containing the chambers 72, his represented as constituted by asingle casting divided into two compartments by the longitudinal centralpartition If. In each of these compartments or chambers there is alongitudinal slot j to permit access to the interior thereof and to themouths of the pipes 111. \Vhen the device is in operation, thelongitudinal slots y' are closed tightly by lids s.

Vhat I claim as my invention is In a rotating heat-transferring device,the combination of two short hollow shafts arranged in line with eachother and constituting journals, a box arranged between said hollowshafts and divided by a longitudinal partition into two chambers whichcommunicate one with the interior of one and one with the interior ofthe other of the so-constituted journals, and a group of pipes nearlysurrounding said box, each one of the pipes having one end connected toone chamber and its opposite end to the other chamber to opencommunication between the two chambers through said pipes, substantiallyas herein described.

In testimony that I claim the foregoing as my invention I have signed myname, in pres- IO ence of two Witnesses,this 24th day of January,

LEOPOLD VON MAY.
